The customer conveyed to us an overriding royalty interest (“ORRI”) as security for the outstanding receivables and agreed to a payment plan to repay all past due amounts. Amounts received by us pursuant to the ORRI have been applied to the customer’s payment obligations under the payment plan. As of December 31, 2010, the customer had repaid all amounts due to us under this agreement therefore our right to the ORRI has been extinguished. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%">In June 2010, a subsidiary of Frontier entered into a charter contract with a subsidiary of BP, plc (“BP”) for the FPSO, <i>Seillean</i>, with a term of a minimum of 100 days in connection with BP’s oil spill relief efforts in the U.S. Gulf of Mexico. The unit went on hire on July 23, 2010. In October 2010, after the Macondo well was sealed, BP initiated an arbitration proceeding against us claiming the contract was <i>void ab initio</i>, or never existed, due to a fundamental breach and demanded that we reimburse the amounts already paid to us under the charter. We believe BP owes us the amounts due under the charter and do not believe BP can successfully make such a claim. The charter has a “hell or high water” provision requiring payment, and we believe we have satisfied our obligations under the charter. Based on the available information and the analysis we have performed to date, we have recorded the revenue under the charter, which was $29 million through the end of the contract. In the event BP is successful in its claim, we would take a charge for revenue recorded. However, we also believe that if BP were to be successful in claiming the contract <i>void ab initio</i>, we would have an indemnity claim against the former shareholders of Frontier, and have put them on notice to that effect. </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringIncludes disclosure of claims held for amounts due a company.
